When it comes to investing in precious metals, two key factors determine the value and desirability of your bullion: purity and weight. At Moon Investments, we believe that understanding these elements is essential for making informed investment decisions. Whether you’re a seasoned investor or new to the world of gold and silver, knowing what to look for in bullion can help you build a strong, secure portfolio.
What is Purity in Precious Metals?
Purity refers to the proportion of a precious metal in a given bullion product. Gold and silver are often alloyed with other metals to improve durability, but investment-grade bullion maintains high purity levels. The purity of bullion is typically expressed in karats (for gold) or as a fineness number (for both gold and silver).
Gold Purity Standards
Gold bullion is commonly available in the following purities:
- 24 Karat (999.9 or 99.99% pure gold) – This is the highest purity level available in investment-grade gold. It is often found in gold bars and some coins.
- 22 Karat (916 or 91.6% pure gold) – Commonly used in Krugerrands and other gold coins, this gold is alloyed with copper for added strength.
- 18 Karat (750 or 75% pure gold) – Found mostly in jewellery but also in some collectible gold medallions.
Silver Purity Standards
Silver bullion also comes in different purity levels:
- 999 (99.9% pure silver) – Standard for investment-grade silver bars and coins.
- 925 (92.5% silver, also known as Sterling Silver) – Used primarily in jewellery and collectible items.
For investors looking to maximise value, we always recommend 99.9% pure silver as the best option for wealth preservation and growth.
How Weight Affects Bullion Value
Weight is just as crucial as purity when considering a bullion investment. Bullion is typically measured in troy ounces, which differs slightly from the standard ounce used in everyday measurements.
Common Gold Bullion Weights
- 1oz Gold Bar – The most popular choice for investors due to its liquidity and affordability.
- 10oz Gold Bar – A solid choice for those looking to make a larger investment.
- 1kg Gold Bar – Preferred by high-net-worth investors and institutions.
- Gold Coins (Krugerrands) – Often minted in 1oz, 1/2oz, 1/4oz, and 1/10oz sizes, offering flexibility in investment amounts.
Common Silver Bullion Weights
- 1oz Silver Coins & Rounds – A great entry point for new investors.
- 10oz Silver Bars – Ideal for stacking and long-term holding.
- 1kg Silver Bar – Popular for serious silver investors.
- 100oz Silver Bar – A larger-scale investment option, often purchased for storage.
At Moon Investments, we offer a wide selection of gold and silver bullion in various weights to accommodate different investment strategies. Whether you’re diversifying your portfolio with smaller denominations or acquiring bulk bullion for long-term wealth storage, we provide the expertise to guide you through the process.
Why Purity and Weight Matter
Understanding purity and weight is fundamental to making sound investment decisions. Here’s why:
- Purity ensures intrinsic value – The higher the purity, the greater the intrinsic worth of your investment.
- Weight determines market value – Precious metals are traded based on weight, so knowing the exact amount you own is essential for pricing and liquidity.
- Resale and liquidity – High-purity, standard-weight bullion is easier to sell and trade globally.
